Suicide Preventive Psychosocial Treatment for Youths

Suicide Attempt - any report from the Columbia-Suicide Severity Rating Scale (C-SSRS) or electronic medical records

Any report of suicide attempt, using data collected from: 1. Youth-report of the C-SSRS. The C-SSRS is a 22-item structured clinical interview assessing the frequency and severity of suicidal ideation, suicidal behaviors, and self-harm. 2. Caregiver-report of the C-SSRS (reduced 4-item version including only the suicidal behavior section). 3. Electronic medical records.

Nonsuicidal self-injury - any report from The Deliberate Self Harm Inventory - Youth version (DSHI-Y)

The DSHI-Y used in this trial is a 8-item clinican-rated interview that will be used to assess presence and frequency (0 to ∞) of non-suicidal self-injury, where a higher score indicates higher frequency of non-suicidal self-injury. One item measuring non-suicidal intoxications has been added to the original DSHI-Y. The DSHI-Y is adapted for adolescents from the DSHI an empirically supported measure of various aspects of NSSI originally developed for use with adults. The DSHI has demonstrated good test-retest reliability and adequate concurrent validity among adolescents. For youths who decline participation in follow-up interviews, a one-item version of the DSHI-Y assessing presence of any nonsuicidal self-injury will be administered to the youth's caregiver when caregiver report is available.

Work and Social Adjustment Scale, youth version (WSAS-Y)

WSAS-Y is a clinician-rated scale of impaired functioning in school, everyday life, friends and social life, recreation and hobbies and family and close relationships. The scale generates a global score ranging from 0 to 40, with higher scores indicating greater impairment.

Children's global assessment scale (CGAS)

The CGAS is a clinician rated single item 1-100 scale that integrates psychological, social, and academic functioning in children as a measure of psychiatric disturbance. Higher values represent better functioning.

Revised Children's Anxiety and Depression Scale, 25 item version (RCADS-25)

The RCADS-25, a shortened version of the Spence Child Anxiety Scale, is a child self-report measure of anxiety- and depression-related psychopathology, with six subscales; separation anxiety, social anxiety, generalized anxiety, panic disorder, obsessive-compulsive disorder and major depressive disorder, as well as a total anxiety-scale. Total range is 0-45, Likert scale ranging from 0-3, with higher values representing a worse outcome.

Self-harm

Composite outcome of suicide attempts (C-SSRS, medical records) and nonsuicidal self-injury (DSHI-Y) ranging from (0 to ∞), in order to enable comparison with other studies.

Borderline Personality Feature Scale for Children-11 (BPFS-C-11)

The BPFS-C-11 is a youth-rated 11-item measure of borderline personality features for children 9 - 18 years old. The BPFS-C-11 includes indicators of borderline pathology such as affective instability, identity problems, and negative relationships. Item responses are on a 5-point Likert scale, yielding a range of 11-55, with higher scores indicating higher levels of borderline features.

Levels of Personality Functioning Questionnaire 12-18 (LoPF-Q 12-18)

LoPF-Q 12-18 is a youth-rated 20-item measure rated on a scale of 0-4, yielding a range of 0-80, where a higher score indicates higher impairment in personality functioning. LoPF-Q is developed for use in adolescent populations between 12 and 18 years to assess the dimensions of personality functioning: identity, self-direction, empathy, and intimacy.

Borderline Symptom List Supplement (BSL-Supplement)

The BSL-Supplement is a youth-rated 9-item measure of self-destructive behaviors under the past 7 days, with answers ranging from "Not at all" to "Daily or even more often". Higher scores indicate a higher frequency of self-destructive behaviors.
